First study to look at facial responses of foetuses to tastes shows crying expression twice as likely for kale than carrotIf the taste of kale makes you screw up your face, you are not alone: researchers have observed foetuses pull a crying expression when exposed to the greens in the womb.While previous studies have suggested our food preferences may begin before birth and can be influenced by the mother’s diet, the team says the new research is the first to look directly at the response of unborn babies to different flavours.

The UK’s new health secretary, Thérèse Coffey, has not taken on an easy job. Almost two-thirds of trainee GPs plan to work part-time just a year after they qualify, reporting that the job has become too intense to safely work more. A record 6.8 million people are waiting for hospital treatment in England, and 132,139 posts lie vacant across the NHS in England. Ian Sample hears from acute medicine consultant Dr Tim Cooksley about what’s happening within the NHS, and speaks to the Guardian’s health policy editor, Denis Campbell, about how the UK’s health and social care systems ended up in crisis and whether they can be fixedArchive: ITV News, BBC Sounds, BBC News, Sky News, BBC Newsnight Continue reading...
Farthest planet from sun and its satellites revealed in unprecedented detail by space telescope’s infrared imagerThe James Webb space telescope has turned its gaze away from the deep universe towards our home solar system, capturing an image of a luminous Neptune and its delicate, dusty rings in detail not seen in decades.The last time astronomers had such a clear view of the farthest planet from the sun was when Nasa’s Voyager 2 became the first and only space probe to fly past the ice giant for just a few hours in 1989.

More than a third of children’s clothing tested in a study detected PFAS, which are used to make textiles stain resistantToxic PFAS chemicals are frequently used to make children’s clothing and textiles resist water and stains, but exposure to the compounds in clothes represents a serious health risk, a new peer-reviewed study finds.The study, published in the Environmental and Science Technology journal, detected the chemicals in 65% of school uniforms, rain gear, snowsuits, snowshoes, mittens, bibs, hats and stroller covers tested, and at levels authors characterized as “high”.

A week certainly is a long time in monarchy. It was fascinating to see individuals actively changed by this experienceA strange thing has happened since last week, when I wrote about how myself and other social psychologists were studying the crowds of people queueing to watch the ceremonials following the death of Queen Elizabeth – finding out the many reasons and motivations for taking part in this mass event. It seems the Queue itself – and what it supposedly tells us about the state of our nation – has become as big a story as the ceremonies. We stopped watching the pageantry and started watching ourselves watching the pageants.This was just the start of a series of remarkable transformations. The size and behaviour of the crowds did not simply reflect the pre-existing state of the nation. Rather, through these crowds we saw a transformation in our desire to participate in the events, a transformation of relations between those in the crowd, and transformations in their relationship to the monarch, the monarchy and the state. A week is a long time, it seems, and not only in politics. Continue reading...

When parents cast a child into the role of mediator, friend and carer, the wounds are profound. But recovery is possibleI came to research the emotional neglect of children by accident. More than a decade ago, I wrote my master’s thesis on the relationship between the personal and professional lives of psychotherapists. How did they manage to keep the distress they heard in their clinics from affecting their own emotional balance? And how did they stop their personal challenges from affecting their clinical work?In our conversations, I asked what brought them to be clinicians. The consistency of their answers surprised me. Virtually all said that being there for others, emotionally, came naturally; they were good at it because they were practised in tending others’ needs since childhood, starting with their own parents. With deeper conversations, I learned of the difficult family circumstances they each came from. Continue reading...
Whether it’s organic or psychosomatic or something in between, multiple chemical sensitivity can cause chronic illness, and its sufferers often feel abandonedSharon calls herself a universal reactor. In the 1990s, she became allergic to the world, to the mould colonising her home and the paint coating her kitchen walls, but also deodorants, soaps and anything containing plastic. Public spaces rife with artificial fragrances were unbearable. Scented disinfectants and air fresheners in hospitals made visiting doctors torture. The pervasiveness of perfumes and colognes barred her from in-person social gatherings. Even stepping into her own back garden was complicated by the whiff of pesticides and her neighbour’s laundry detergent sailing through the air. When modern medicine failed to identify the cause of Sharon’s illness, exiting society felt like her only solution. She started asking her husband to strip and shower every time he came home. Grandchildren greeted her through a window. When we met for the first time, Sharon had been housebound for more than six years.When I started medical school, the formaldehyde-based solutions used to embalm the cadavers in the human anatomy labs would cause my nose to burn and my eyes to well up – representing the mild, mundane end of a chemical sensitivity spectrum. The other extreme of the spectrum is an environmental intolerance of unknown cause (referred to as idiopathic by doctors) or, as it is commonly known, multiple chemical sensitivity (MCS). An official definition of MCS does not exist because the condition is not recognised as a distinct medical entity by the World Health Organization or the American Medical Association, although it has been recognised as a disability in countries such as Germany and Canada.

Against a backdrop of a cost of living crisis caused in part by soaring energy prices, the UK’s new prime minister, Liz Truss, appointed MP Jacob Rees-Mogg as secretary of state for business and energy. In this role, Rees-Mogg will have to tackle these issues while being responsible for the UK’s legally binding target of net zero greenhouse gas emissions by 2050. It is a goal he has previously described as ‘a long way off’. Madeleine Finlay hears from environment correspondent Fiona Harvey about his plans to extract ‘every last drop’ of oil and gas from the North Sea, the possibility of fracking in the UK, and the importance of energy efficiency and renewables in addressing the cost of living, energy and climate crises togetherArchive: BBC News, Channel 4 News, The Telegraph Continue reading...

Research shows early birds more sensitive to insulin levels and burn more fat at rest and during exerciseNight owls may be more prone to heart disease and diabetes than early birds because their bodies are less able to burn fat for energy, US researchers say.People who rise early rely more on fat as an energy source, and are often more active in the day, than those who stay up later, meaning fat may build up more easily in night owls, the scientists found.

State is the fifth to legalize environmentally friendly process that allows for natural reduction of human remains to soilCalifornia lawmakers have approved a new way of returning those who have died to the earth, after Gavin Newsom signed into law a bill allowing human composting on Sunday.Cremation, which accounts for more than half of burials, is an energy-intensive process that emits chemicals such as CO into the air. Through human composting, or natural organic reduction (NOR), the body is naturally broken down into soil. Continue reading...
Shuffling and studying the pictures on tarot cards can be like a moment of meditationMy first attempts with tarot readings began on a camping trip with a couple of close friends and their friends.

Snakes coiled near us. Continue reading...
Findings will help build more accurate picture of how often space rocks crash into red planetResearchers have located fresh craters on Mars using shock waves caused by lumps of space rock as they tear through the sky and slam into the ground.The new scars on the face of the planet are the first impact craters ever traced from the bang and crash of hurtling meteoroids bombarding another planet. The findings will help scientists build a more accurate picture of how often Mars is battered by the solar system’s rocky detritus and refine their understanding of the deep internal structure of our planetary neighbour.

The right kind of argument can apparently bring couples closer together. Is bickering about the bread bin a good start?I want to get better at arguing. Not the bitter, exhausting kind that happens online, and not the kind that occurs when you put two French people in a room and within 90 seconds one of them is quoting Montaigne and the other has countered with Immanuel Kant, even though they are talking about, say, low-energy lightbulbs (about which neither of them previously had an opinion).I’m interested in the domestic. I have never mastered the short, sharp spat, which can apparently be quite therapeutic. I wouldn’t know. After an early phase of massive, horrible fights, my motto for decades has been: “Why say something when you could let it fester, explode at the worst possible time, be horrified and grovellingly row back until the next time?” Continue reading...

Studies show that women with heart disease are more likely to be misdiagnosed than men, and will have worse outcomes for surgery. What is behind this bias and how can how it be fixed?Heart diseases are still chronically misdiagnosed or underdiagnosed in women. With depressing regularity, we see stories of women failed by the health system when they come to hospitals with the symptoms of a heart attack. As a professor of cardiac science with 40 years’ experience, for me it has been a frustrating journey to get to the real cause of this problem: a combination of professional, systemic and technical biases. The experiences of individual patients are complex to analyse and interpret, but now we can view these effects on a much bigger scale.Women are 50% more likely to receive a wrong initial diagnosis; when they are having a heart attack, such mistakes can be fatal. People who are initially misdiagnosed have a 70% higher risk of dying. The latest studies have similarly shown that women have worse outcomes for heart operations such as valve replacements and peripheral revascularisation. As well as being misdiagnosed, women are less likely to be treated quickly, less likely to get the best surgical treatment and less likely to be discharged with the optimum set of drugs. None of this is excusable, but is it understandable? Continue reading...
People you don’t see face to face can still provide a communityI was raised not to talk to strangers. Strangers, I was taught as a child, are people we’ve never met before, therefore we don’t know them. Childhood me would have been horrified to know that, now in my 30s, I frequently engage with complete randoms without giving it much thought. I’m not just talking about shop staff who make the mistake of asking me how my day is going, only to be met with a very honest, over-sharing response. I mean the way that social media apps have evolved to illicit a reaction or response, how my thumb reflexively double-taps a metronome as I scroll, giving iambic rhythm to the red hearts that pulse before my eyes. I am not alone in counting people I’ve connected with online as my friends, but how do these friendships compare to those we have in person?There is a certain ease in making online connections that can’t be replicated offline and it’s this ease that appeals to the time-poor, emotionally guarded side of me. Follow? Follow back, job done! While I had a large group of friends at secondary school, I wouldn’t say I am now part of anything that looks like Taylor Swift’s #squadgoals, a term often used to describe her large yet intimate circle of friends. Nor would I know how to go about getting a squad. According to Dr Marisa G Franco, psychologist, friendship expert and author of Platonic, making friends as an adult is more complicated than when we were kids. “Children in school have what sociologists consider the essential ingredients for friendship to happen organically, which is repeated unplanned interaction and shared vulnerability. As adults, we don’t really have environments with those elements, because at work we’re maybe more guarded and less vulnerable, even if we see each other every day.” Continue reading...

Research says clicks emitted from whales’ heads are symbolic marking like human social expressionSperm whales are among the deepest divers on the planet. They are natural submarines, spending 70% of their time foraging for squid in the dark ocean for up to 80 minutes at a time. When they break through what Herman Melville called “the ocean’s skin”, they socialise, twisting and turning their grey bodies around one another in a sensual, enigmatic choreography.They measure up to 18 metres long and have the biggest brains on Earth. For at least 200 years, scientists have wondered what these mammals do with those brains. Now, evidence has emerged that may revolutionise the way we think about whales. Continue reading...

Theory of inner satellite ripped apart by gas giant’s gravity 100-200m years ago also explains rings’ relative youthSaturn’s famous rings could be the aftermath of a moon that was ripped apart by the planet’s gravity, according to scientists.The research, based on data from the final stage of Nasa’s Cassini mission, suggests that Saturn may have been ringless for almost all of its 4.5bn-year existence. But about 160m years ago, an inner moon strayed too close to the gas giant causing it to be pulled apart, painting out its own orbit in a trail of shattered icy fragments. Continue reading...

Despite what we hear from the media, the reasons so many are gathering are complex and variousBritain is in mourning. This is affirmed every time we turn on the television and see the huge numbers of people watching royal processions, or willing to queue for long hours to file past the Queen’s casket. They have gathered, we are told, “to pay their respects”. They are there “to thank the Queen”. Above all, they are “united in grief”. In this way, a picture is built up of a homogenous national community defined by its love of monarch and monarchy. But things are not that simple.I am part of a team of social psychologists who have long been interested in collective behaviour, and we are investigating the crowds at the various ceremonial events in Edinburgh and London. We are interested in why people gather, how they experience these gatherings and the consequences – both for the individual and for society – of their presence. The first thing we have learned is that any attempt to reduce crowd participation to a single, universal motivation is a distortion. People come along for many different and mixed reasons, not all of which involve allegiance to the monarchy.Stephen Reicher is a professor of psychology at the University of St Andrews, a fellow of the Royal Society of Edinburgh and an authority on crowd psychology Continue reading...

According to the World Health Organisation, air pollution causes 7 million premature deaths every year. We’ve known for a long time that air pollution causes lots of health problems, including lung cancer – but exactly how the two were linked was somewhat of mystery. Last week, a team from the Francis Crick Institute and University College London presented findings that shed new light on the role between air pollution and lung cancer. And, in doing so, could make us rethink how cancer develops.Madeleine Finlay speaks to the Guardian’s science correspondent Hannah Devlin about how scientists uncovered this link – and what it might mean for the future of the field.Archive: Channel 4 News, BBC News, European Society for Medical Oncology Continue reading...
Transition to blue light radiation across Europe increases suppression of sleep hormone melatonin, say scientistsBlue light from artificial sources is on the rise, which may have negative consequences for human health and the wider environment, according to a study.Academics at the University of Exeter have identified a shift in the kind of lighting technologies European countries are using at night to brighten streets and buildings.

Shrimp-like Cystisoma are protected from predators by being virtually invisible – thanks to unique retina and a body that casts almost no shadowThe inky depths of the ocean’s twilight zone are home to fist-sized shrimp-like crustaceans with ridiculously big eyes. Most of Cystisoma’s head is taken up by its eyes – all the better for seeing in the dark. “The bigger you make your eye, the more likely you are to catch any photons that are out there,” says Karen Osborn, research scientist at the Smithsonian Institution in Washington DC.A big challenge for animals living in deep midwater, in Cystisoma’s case between 200 and 900 metres down, is to see while not being seen by predators. “It’s basically like playing hide and seek on a football field,” says Osborn. “There’s nothing to duck behind.”
